Our invention relates to a method'of packaging and fluid substances adapted to solidify, such as cheese and the like.

An object of the invention resides in providing a method of packaging and dispensing in which the substances to be. packaged may be readily poured in the original container from which the same is to be dispensed and in which the substance may be readily dispensed from the same package.

An object of the invention resides in providing I a method'of packa ing and dispensing in which a tray is used having a bottom and lateral walls hingedly connected thereto and in which a hoop is used for holding the tray in erected position, said method consisting in apphring a cover to the tray and hoop and in attaching the cover to the hoop when the cover is applied to the tray and hoop to cause simultaneous removal of the cover and hoop to free the walls of the tray.

Other objects of the invention will become apparent from the following description of the in- .vention.

This application for patent is a division of our copending application Patent No. 2,284,959

granted June 2, 1942. For the purpose of illustrating our method, we

7 have shown a package which comprises a tray A best illustrated in Figs. 4 and 9, a hoop B shown in detail in Fig. '1 and acover C illustrated in Fig.

g. These parts cooperate in a manner to form a -package which is particularly adapted for use with our method. The saidparts will now be individually described in detail.

; The tray A is constructed from a blank ll Fig. 6 which is made from cardboard or shown in some other suitable paper material. This blank .is formed 7 with a number of transverse scores It, u il, ll, I1, I. and ll. These scores divide the blank into a bottom 2!, side walls 22 and 23 hingedly connected thereto, flanges 24 and 25 hingedly connected to the side walls 22 and 23,

versa. In the fabrication of the blank, the flaps 28 and 20 are coated with adhesive along the marginal portions thereof adjoining the edges and II of the blank. The coating falls short of the scores I! and I! by a distance equal to the width of the flanges 24 and 25. After being coated, the

m. 11 is a perspe'ctiveview showing the hoop applied to the structure disclosed in Fig. i0.- rig. lsris a perspective view oithetray-nlled and with the wrapper closed and showing thef package before the cover has been applied.

In the packaging of cheese and similar substances which are poured in a liquid state in a container to be subsequently removed therefrom after solidification. considerable diillculty has been encountered in procuring access to the subbla'nk is folded along the scores I! and II and the adhesive of the flaps 28 and 29 caused to adhere to the bottom 2|. The blank is now completed and ready for use. From Fig. 6, it will be apparent that the score it is oil-set from the score It a distance substantially equal to the width of the flange 2t. Similarly. the score I! is oil-set from the score I! a distance equal to the width of the t .flanges 2'. By means'of this construction, the 'wall ills adapted to becomespaced from the auxiliary! andsimilarly, the wall 23 is adapted to become-spaced "fl'Ol'iI- the auxiliary wall 21 when the walls of the tray are folded into. erected podtion. At the same time the flanges 2t and ii are caused to extend outwardly from the walls 22 and 23 and at right angles thereto. The arrangement oi the parts, when the carton is stance The present invention provides a method be erected, is best shown in Fig. i).-

The hoop B, as stated. is best shown in Fig. 7 and is constructed irom a strip of cardboard or othersuitable material of a width equal to the height pf the lateral walls of the tray A. This strip is scored at the four corners, ks indicated at 31, 38, 38 and 4|, to form lateral walls 22a, 23a. lla and 32a and afiap 42 connected with the wall 22a. The fiap 42 is adapted tobe secured to the end wall 31a by adhesive or otherwise'and ties the end of the hoop B together. The hoop B is adapted to be applied over the walls of the tray A or in other words, said tray is adapted to be received within the said hoop and to telescope with reference thereto. Inasmuch as the walls of the tray A are disconnected at their adjoining edges, the hoop B holds the walls from spreadhis and maintains the tray in erected form.

The cover C is constructed from a blank of paper cardboard or some similar paper product which is best shown in Fig 2 and 3. This blank is formed with longitudinal scores 43 and 44 and with transverse scores 45 and I which divide the blank into a top 41, end walls tlb and 32b, and side walls 221; and 231). In addition, the blank is cut along the scores 44 and 43 up to the scores 45 and 46 to form fiaps 48 which are folded back and secured to the end walls ilb and means of adhesive or otherwise. The side walls 22b and 23b of the cover C are formed with diagonal scores 49 which permit of collapsing the carton so that the same may take the form shown in Fig. 2.

The cover C is constructed at the lower portions of the side walls 22b finger notches ii. In like is constructed with similar and 23b thereoi. with manner, the hoop B finger notches II which, when the parts are assembled, areadapted to register with one another. These finger notches permit 01' grasping the tray A at the lowermost portion thereof the cover C to remove the tray from the cover.

The hoop B is held attached to the cover C by means of a number of locking tongues 53. These tongues are struck out oi the material forming the side walls 22a and 23a and are integral with the end walls tin and 32a. The scores 31, 3|, SI and 4| do not extend across these tongues so that. when the structure is folded, the tongues remain in the planes of the end walls Sin and 32a and extend outwardly from the side walls and by manipulating tended portion N of the wrapper or container '2 "b by 22a and 23a, as shown in Fig. '7. For cooperation "with these tongues, a number of slots II are cut 1nthe side walls 22b and 23b of the cover C. When the hoop B is inserted into the cover C,

tongues 63 engage said slots and holds the hoop attached to the cover.

The manner oi using the invention is as follows: The cheese or other substance to be packaged in theipackage is usually wrapped in paper, tin foil or some other suitable wrapping material. For this purpose, a sheet of such material is placed upon the tray A when said tray is collapsed, which sheet is indicated by the reierence numeral 6|. By means of suitable machinery, now available for the purpose, the sheet is folded to form a container 82 open at the top, the excess portions of the sheet being doubled back upon themselves at the ends of the package and overlapping one another as indicated at '8 in Figxlil'of the'drawings. The lateral walls of the is then folded over upon the melted cheese as shown in Fig. 12. The cover C is next applied to the entire assembled structure and during such application, the tongues I; are forced into the slots 84 and the lower edges ll of said slots which form shoulders engage corresponding shoulders It on the said tongues and hold the hoop secured to the cover C. Whenever it becomes desirable to remove the contents of the package, for the impose of dispensing the contents, the finger and thumb may be placed in the finger notches II an I2 and the lowermost por- 'tion of the tray A readily grasped. This tray may now be removed from the cover. Due to the fact that the hoop B is locked with reference to the cover C, the hoop remains in the cover and the tray and contents are separateLv withdrawn from the hoop and cover. Upon removal of the cover and hoop, the lateral walls of the tray A are free and may be swung outwardly into collapsed position; as shown in Fig. 4. When so disposed, the solidified cheese is exposed and the wrapper or container 02 envelopm hadto the cheese. .Where a part only oi the eheese'is used, the walls of the tray may be folded intoerected position and the cover with the hoop attached same. If desired, two or all or the lateral walls of the tray may be broken away at the scores iorming the hinges between the same and the blottomof the tray'to facilitate application of the cover thereto. We have found that, where the Q id walls only are broken away. the side walls may be readily held'in erected position, while the cover is being applied to' the tray. In such case, the ends of the side walls hold the tray from longitudinal movement relative to the cover.

While we have described the locking tongues for holding the hoop attached to the cover, it can readllybe understood that the method will embrace the use of glue for attaching the hoop to the cover while the parts are being assembled which would.,.cause the same to stick together similar fiuid substances adapted to solidify. By,

our improved method, the original container in which the cheese is poured may be readily ma}. nipulated to expose the cheese when desired fer. use, whereby the same may be easily and quicltly, dispensed. By means of our'invention, the hoop used with the container is simultaneously removed with the cover so that the lateral walls of the .tray are free to swing outwardly and extray A are also folded up to fit the walls of the "container so formed. This may be done at the same time the container is formed or it may be done subsequently. The structure is-then inpose the contents of the tray.

Changes in the specific steps of our invention as herein disclosed. may be made within the scope of what is claimed without departing from the spirit of our invention.

Having described our invention, what we claim as new and desire to protect by Letters Patent is:

l. The method oi packaging and dispensing the same may be easily removed and access again applied to the tray to close the fluid substances adapted'to solidify. said method consisting in placing on a tray having a bottom and lateral walls hingedly connected therewith a sheet, in folding the sheet to form a container, in erecting the lateral walls of the tray to flt about I said container, in applying a hoop to the lateral walls to hold-the same erected, in pouring the substance to be packaged into the container to substantially the height of the lateral-walls oi,

the tray, in folding over the sheet to enclose the substance packaged and in applying a cover to the hoop.
